How to see when a ChatGPT message was sent
Updated May 27, 2026
Quick answer
ChatGPT does not display the time individual messages were sent. You can see the conversation in your history, but the actual send times are hidden. GPT Master pulls timestamp data directly from the ChatGPT API (the same data the page already loads) and displays it inline above every message in the format "Mar 11, 1:00 AM". Hover any timestamp for the full weekday. No cap on any tier.
Knowing when a message was sent matters more than it sounds. You might want to check whether advice was given before or after a news event, verify when you made a decision, or just understand the timeline of a long conversation. ChatGPT does not show any of this. GPT Master does, with no extra API calls required.

Read timestamps above each message
Look directly above each message (yours and ChatGPT's alike) to find the timestamp. The format is "Mar 11, 1:00 AM" for messages from the current year. Older messages include the year: "Mar 11 2025, 1:00 AM".

Hover for the full weekday
Move your cursor over any timestamp to see the full date including the day of week, such as "Tuesday, March 11, 2025, 1:00 AM". This is useful when you need to know exactly what day of the week a message was sent.

Frequently asked questions
- Where does GPT Master get the timestamp data?
- The timestamps come from the ChatGPT API, which already returns this data when the page loads. GPT Master reads it and displays it inline. No extra network requests are made.
- Are timestamps available for older conversations?
- Yes. Timestamps are shown for every message in every conversation, regardless of age. Older messages display the year alongside the date and time.
- Do timestamps show in relative format like "5 minutes ago"?
- No. GPT Master shows absolute timestamps only: the exact date and time. This makes the information reliable and consistent regardless of when you are reading the conversation.
- Is there a cost to see timestamps?
- Timestamps are available to all GPT Master users with no tier restrictions. Install and they appear automatically.
